CDC recommends better quality masks or double masking
To prevent getting and spreading COVID-19, the CDC suggests ways to improve how your mask protects you. One strategy is to use a cloth mask that has multiple layers of fabric. Another way to improve mask fit and filtration is by wearing two masks.
To help residents stay properly masked, and wear two masks if they want to follow the latest CDC guidance, SHA is distributing masks in most communities. Residents who missed mask delivery or need more can call 206.239.2589.
